run_modes()


        $webapp->run_modes(
                 start        => 'start',
                 choose_type  => 'choose_type',
                 submit_order => 'submit_order',
               );

Does 2 things:

Registers valid values of the mode_param().

If the CGI query passes in any other run_mode name,
the application will die.

Maps the parameter names to run-mode methods:
(subroutines contained in this module)

Thus, if the CGI query includes

the parameter 'mode'
with a value of 'choose_type',

then $webapp->choose_type() will be called.

Alternative syntax:


      $webapp->run_modes([qw(start choose_type submit_order)]);

(Less flexible, but less typing)
